Emma said: “The letter came through yesterday. As soon as I got it I was speechless. I don’t understand why they think I would deliberately do something like that.

“As if I just have mice lying around I can throw in a pasta box. It’s ridiculous.

“It could easily have been put there by someone at the factory in Italy.”

The 28-year-old, who wed husband Ross, 39, in July, said she was only offered a £10 voucher from the supermarket giant.

She added: “They haven’t even apologised, that’s all I want.”

A Tesco spokesperson said: “We were very concerned to hear of this incident and have fully investigated with our supplier.

"Following extensive tests and analysis, we are confident that the pasta was not contaminated when it was produced and packed, and have given Emma a gesture of goodwill to thank her for her patience while we looked into this matter.”
